Comment 10 for bug 1630946

So for this bug we need:
1. make it a recommends
2. ubuntu-meta update for cosmic

For #1 I opened [1] and #2 can only follow after that is merged.

And this can be done independent to bug 1755858 - so no matter if we succeed/fail there one can at least later remove open-iscsid if he wants without taking out the ubuntu-server meta.
